Preparation method of high-strength high-elasticity wear-resistant CuNiSn alloy material through vacuum induction melting

The invention provides a preparation method of a high-strength high-elasticity wear-resistant CuNiSn alloy material through vacuum induction melting, and belongs to the technical field of non-ferrous metal alloy preparation. Comprising the following steps: (1) burdening; (2) charging; (3) vacuumizing; (4) smelting; (5) casting; (6) discharging; the CuNiSn alloy is prepared by adopting a vacuum induction melting method, the material composition is reasonable, the structure is uniform, the alloying degree is high, no obvious structure defect exists, no impurity exists, and after a small amount of Fe, Si and Al is added, the material strength is improved, the wear resistance is improved, grains are refined, and no reverse segregation of Sn exists in the structure; the nano carbon sphere micro-arc oxidation coating is sprayed on the surface of the CuNiSn alloy, so that the strength of the alloy is improved, the friction coefficient is obviously reduced, and the wear resistance of the alloy is obviously improved;
